UNSPSC 41113900: Soil measuring equipment

UNSPSC 41113900 Soil measuring equipment is a Class code encompassing specialized instrumentation and laboratory testing services for soil characterization, materials inspection, and structural analysis that state and local governments procure during transportation infrastructure projects, building construction, and utilities maintenance. State and local buyers under this code include transportation departments, municipal public works offices, utility authorities, and fire district capital improvement programs. The scope extends beyond soil testing narrowly defined to include comprehensive construction materials testing and inspection services—concrete compressive strength testing, reinforcing steel and structural welded steel inspections using ultrasonic and magnetic particle methods, masonry unit and mortar testing, and electrical insulating oil sampling and laboratory analysis per ASTM specifications. Truck-mounted cone penetrometer test (CPT) sounding units represent one equipment class; materials testing firms providing field and laboratory services on fixed unit-price or time-and-materials bases represent another. A single issuing body—Keys Energy Services (the Utility Board of the City of Key West, Florida)—has posted multiple RFPs for the same service category within recent months, signaling repeat procurement activity in the electrical testing domain.

Recent opportunities span Michigan, Connecticut, Florida, California, and Texas. The Michigan Department of Transportation (MDOT) posted RFP 260000002268 on June 26, 2026, requesting proposals for a truck-mounted cone penetrometer test sounding unit with a July 16, 2026 response deadline, specifying a newly manufactured 20-ton system with integrated load-sense hydraulics, dual data acquisition systems, and Medusa dilatometer capability, with award to the responsive and responsible lowest-price bidder meeting pass-fail criteria. The Town of Waterford, Connecticut, released RFP26009 on April 21, 2026, soliciting materials testing firm proposals for special inspector and construction materials testing services on the Oswegatchie Fire Station project, due May 5, 2026, requiring ACI, AWS, ICC, or ASNT certified personnel and fixed unit pricing with no escalation permitted. Keys Energy Services (City of Key West, Florida) posted RFP 1026 on April 6, 2026, seeking sealed proposals for electrical insulating oil testing of 28 power transformer main tank units, 13 load tap compartment units, and 10 voltage regulator units over a three-year base term plus two optional one-year renewals, with responses due April 17, 2026. The Harris County Flood Control District (Texas) issued an RFSQ on January 30, 2026, for on-call construction materials engineering and testing services supporting stormwater detention basin, channel repair, and occasional bridge projects, with statements of qualifications due March 2, 2026, evaluated on a 100-point scoring system based on firm experience, capacity, and methodology under Texas Government Code 2254.004, with MWBE participation goals applicable to subsequent individual project awards and a five-year registration period expected to begin April 2026.
